Guatemala.com,  Mobile Application Developer

August 2018 - January 2019

Successfully created the new version of the Guatemala.com mobile app from scratch unifying all of the contents of the project going from news, sports, events and a directory in the app in a period of 3 months and the app reached an average of 20K monthly active users. Previous to this version of the app, the development was being made by a third party and the company was looking for a way to have faster development cycles internally so I suggested the use of hybrid mobile technologies with Apache Cordova, Angular & Ionic and was put in charge of the project saving the company more than 3 months in time and development costs by having only one development cycle instead of two separated for iOS and Android. Apart from the frontend, I also developed several RESTful API endpoints with OAuth capabilities in Laravel to provide the information needed in the app.
